摘要
以糙皮侧耳(Pleurotus ostreatus)、白黄侧耳(P.cornucopiae)和肺形侧耳(P.pulmonarius)3个种20个菌株为材料,研究温度、空气相对湿度等环境因素以及培养料配方和菇潮等对细菌性黄斑病发病的影响。结果表明:糙皮侧耳、白黄侧耳和肺形侧耳种间对细菌性黄斑病的抗性无显著性差异,种内不同菌株间存在显著性差异;不同出菇温度条件下,病情指数存在显著性差异;在20℃时病情指数最高,25℃和30℃时病情指数相对较低;80%～85%和95%～100%两个不同湿度条件下,没有显著性差异;在试验范围内,随着培养料中玉米粉含量的增加,子实体的病情指数显著降低;与第一潮相比,第二潮的病情指数显著升高。
The effects of fruiting temperature, relative humidity, cultivation substrate composition and flush number on the incidence of brown blotch disease affecting 20 Pleurotus ostreatus, P. cornucopiae and P. pulmonarius strains were determined. No significant differences in resistance to brown blotch disease were recorded at the species level but resistance levels of some strains within a species were highly variable. Highest disease index values were recorded when the fruiting temperature was set at 20℃ compared with 25℃ or 30℃, but no significant differences in the index values were observed when the relative humidity was maintained between either 80% -85% or 95% - 100%. Under the test conditions, disease index values decreased significantly with increasing supplementation of the cultivation substrate with corn flour （5%, 10%, 15%）, and increased noticeably among the second flush of fruit bodies compared with the first flush.
